Embodiment
As shown in Figure 1 and formed with the form of floating caliper disc brake at this with 10 vehicle brakes totally represented, it comprises housing 12 in known manner, is provided with the floating caliper 14 be fastened on brake disc (not shown at this) on the housing movably.
Hydraulic pressure cavity 16 is positioned at housing 12, in this hydraulic pressure cavity, can seal movably accommodate brake piston 17 along its longitudinal center axis A.In order to give hydraulic pressure cavity 16 supplying hydraulic fluid, be provided with joint 20 in the outside of vehicle brake 10, this joint is connected with at the braking supercharging/master cylinder unit of this unshowned retardation pressure generation unit as carried out start by braking pedal.When operating this retardation pressure generation unit, the hydraulic fluid in hydraulic pressure cavity 16 is pressurized, thus brake piston 17 is moved to left along axis A, so that mobile friction lining 18,19 frictional engagement is to unshowned brake disc.At the end of the operation of this retardation pressure generation unit, hydraulic fluid can flow out hydraulic pressure cavity 16, flows back to towards this retardation pressure generation unit, and result makes brake piston 17 travelling backwards along axis A, serves as a contrast 18,19 move the joint departed from brake disc to make friction.The radial seal represented with 22 seals up the brake piston 17 in hydraulic pressure cavity 16, and this radial seal so helps reset brake piston 17, that is, according to " returning (Rollback) " principle, it applies elastic-restoring force on brake piston 17.The function of the above-mentioned disk type braker 10 caused by hydraulic operation and the further structural texture of disk type braker 10 are known for a person skilled in the art, therefore without the need to being further explained.
For the above-mentioned functions making shown vehicle brake 10 not only complete hydraulic work break, and Parking Brake or parking brake can be served as, be provided with the screw/nut mechanism totally represented with 24, it comprise coaxially arrange with axis A and the internal thread 32 that coordinates with outside thread 28 of the leading screw 26 and having with outside thread 28 be the feed screw nut 30 (also seeing Fig. 2) of sleeve-shaped substantially.
Fig. 3 more clearly illustrates the structure of screw/nut mechanism 24.As shown in the figure, feed screw nut 30 is made up of two parts and comprises the first component 34 of sleeve-shaped, and the left part 36 in the drawings of this first component is equipped with internal thread 32.Look over from left part 36, the external diameter of first component 34 increases on the direction towards the right part 38 in figure slightly according to shown mode, wherein at right-hand member (namely, one end away from end 36) define radial support face 40, screw/nut mechanism 24 by this supporting surface by being that the cod of needle bearing 42 form is rotatably supported in (see Fig. 1) on the housing 12 of vehicle brake 10 at this.Concave surface 44 extends within the right part 38 of first component 34 from supporting surface 40, and the cross section of this concave surface is here polygonal.Concave surface 44 is for holding to form fit the second component 46 of feed screw nut 30 in the circumferential, and second component has with hollow stub shafts 48 in the polygonal formed with the form of concave surface 44 complementation for this reason.In the state be connected with first component 34, the longitudinal center axis A of brake piston 17 is also the first component 34 of leading screw 26 and feed screw nut 30 and longitudinal center's axis of second component 46.Another minor axis 50 with circular cross section is connected with polygonal minor axis 48 one.Bindiny mechanism 52 for outer buttons rotary driving device is formed in this minor axis 50, and here in inner multi-groove structure form.By means of connecting mechanism for rotating 52, unshowned rotating driving device can drive feed screw nut 30 to rotate in both rotational directions, to turn leading screw 26 entering and leave feed screw nut 30, and then changes the effective length of screw/nut mechanism 24.But this leading screw 26 guarantee can not common rotation time just onset.This so accomplishes in an illustrated embodiment, namely, make leading screw 26 have mushroom leading screw head 54, this leading screw head is equipped with multiple radial protrusion 56 on its outer circumferential face, and these radial protrusions join in the axial notch 58 arranged on the inner peripheral surface of hollow cylindrical brake piston 17.Especially as shown in Figure 2 and Figure 4, because radial protrusion 56 and axial notch 58 interact, so leading screw head 54 is directed axially with not rotating manner in brake piston 17.
Thus, screw/nut mechanism 24 is used to the movement rotation of feed screw nut 30 being converted to leading screw 26, to make brake piston 17 shift to unshowned brake disc in this way and friction lining 18,19 is pressed to (parking braking function) on brake disc.Especially can be as shown in Figure 2 and Figure 5, this two width figure all represents the state that withdraws completely (namely removing parking braking state) of screw/nut mechanism 24, whole mechanism is because it is contained in the hollow component of brake piston 17, and because of the first component 34 of feed screw nut 30 and the boring structure of second component 46 closely, and only slightly stretch out from brake piston 17 in this case.
In order to rotary actuation feed screw nut 30, such as, can use motor (not shown), this motor can transmit its rotational motion to feed screw nut 30 by output shaft, and this output shaft is to be formed with the shape of connecting mechanism for rotating 52 complementation.Screw/nut mechanism 24 is self-lockings, and its length change thus realized by the rotation of feed screw nut 30 is always kept after rotary actuation stops.Therefore independent stop mechanism is not needed.
When leading screw 26 is screwed out from feed screw nut 30 because feed screw nut 30 rotates, the end face of leading screw head 54 touches the bottom surface of 60 of brake piston 17.In order to obtain best abutting, the end face of leading screw head 54 and the bottom surface of piston head 60 are formed with complementary type with regard to shape, thus leading screw head 54 large size and being thus close on brake piston 17, allow thus to transmit large latching force well. protective material
In order to unlock the vehicle brake 10 be locked because of the length increase of screw/nut mechanism 24, feed screw nut 30 must be made to rotate in the opposite direction.Subsequently, again leading screw 26 is screwed in feed screw nut 30, and leading screw head 54 departs from the bottom surface of piston head 60, no longer include latching force thus and be delivered to brake piston 17.
In order to this remove operation in prevent leading screw head 54 from being screwed home too at full tilt on feed screw nut 30, this may be leading screw 26 entirely withdraw contingent situation in state; On the other hand, in order to form the reference position of the state that entirely withdraws corresponding to screw/nut mechanism 24, leading screw head 54 is equipped with on its bottom surface 62 towards feed screw nut 30 that recess 64, Fig. 3 that circumference extends is clear illustrates this recess.Recess 64 starts to be quite shallow flat, and its degree of depth is increasing continuously towards front-end face 66 in the circumferential, this front-end face formed recess 64 end and as backstop, as will be explained.
In order to interact with the recess 64 in the bottom surface 62 of leading screw head 54, be formed with protruding 68 in the front end towards leading screw head 54 of feed screw nut 30, this projection is formed according to the shape with recess 64 complementation.Therefore, protruding 68 in the sloping platform shape with semi-circular cross-section, and it highly increases from the beginning to the end continuously.Protruding 68 end at stop surface 70 (see Fig. 3), and this stop surface stops withdrawing further of leading screw 26 when arriving said reference position against the front-end face 66 of recess 64, thus leading screw 26 can not be screwed onto head in feed screw nut 30.
According to favourable mode, the part 72 of the first minor axis 48 is near another minor axis 50 of second component 46, and described part 72 is designed to have circular cross section and as the centering face of needle bearing 42.
As mentioned above, in the operating process of vehicle brake 10, hydraulic pressure cavity 16 is filled with hydraulic fluid, and its pressure ensure that brake piston 17 is moved to be pressed on unshowned brake disc by friction lining 18,19.Hydraulic pressure can be born for making the whole transverse section of brake piston 17, in above-described embodiment of screw/nut mechanism 24, in the first component 34 of feed screw nut 30, be provided with multiple radial hole 74 (see Fig. 1 and Fig. 3), the inside of screw/nut mechanism 24 is drained and filling liquid hydraulic fluid by these radial holes.
Fig. 6 illustrates the longitudinal section of a variant embodiment of screw/nut mechanism 24 ', and here, the first component 34 of feed screw nut 30 does not have such hole 74.On the contrary, the second component 46 of feed screw nut 30 has the passage 76 of substantial axial extension on its outer circumferential face, this passage extends past the whole length of polygonal minor axis 48, therefore arrives the position below the radial inner peripheral surface being positioned at needle bearing 42 vertically from the hollow lumen 78 of screw/nut mechanism 24 '.So, by the cod in needle bearing 42 form, between hollow lumen 78 and hydraulic pressure cavity 16, produce fluid be communicated with connection.The processing of such axial passage 76 is more more economical than the processing of radial hole 74.
If it is not the design form connected in polygonal as described above that the anti-rotating between the first component 34 of feed screw nut 30 and second component 46 connects, but the form that such as engagement connects in tooth, such as in multi-groove structure form, then the backlash that axial passage 76 also can easily be connected by tooth engagement is formed.
The axially mounting of screw/nut mechanism 24 ' is designed to screw/nut mechanism 24 just the same, namely, realized by the supporting surface 40 of first component 34 and another supporting surface 80 on feed screw nut 30 second component 46, another supporting surface 80 described be arranged radially in surface 40 inside and flush with this surface 40.
